Birch leaf: looks kind of like a triangle with spiky grooves, serrate margin.

Oak leaf: Looks like a feather, ondulate (wavy)margin.

Horse chestnut: Looks like a teardrop, entire margin.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
